• Pd-Catalyzed Regioselective C–H Alkenylation and Alkynylation of Allylic Alcohols with the Assistance of a Bidentate Phenanthroline Auxiliary
  作者：Shibo Xu、Koji Hirano、Masahiro Miura

  DOI：10.1021/acs.orglett.0c03444

  日期：2020.11.20

  A Pd-catalyzed regioselective C–H alkenylation of allylic alcohols with electron-deficient alkenes has been developed. The key to success is the introduction of bidentately coordinating phenanthroline directing group, which enables the otherwise challenging and regioselective C–H activation at the proximal alkenyl C–H bonds over the conceivably competitive allylic C–O bond activation. The same Pd/phenanthroline

  已开发了钯催化的烯丙基醇与电子缺陷型烯烃的区域选择性C–H烯基化反应。成功的关键是引入双配位菲咯啉指导基团，该基团可以使在烯基C–H键近端的竞争性和区域选择性C–H激活超过竞争性的烯丙基C–O键激活。相同的Pd /菲咯啉系统对于烯丙基醇与炔基溴的C–H炔基化反应有效。
